Description

  The present invention relates to a nailing machine for manufacturing a gaming machine, and more particularly to a nailing machine for manufacturing a pachinko machine.

 A large number of nails are driven into a game board, particularly a game board for a pachinko machine. As an apparatus for driving a large number of nails, there is an apparatus described in Patent Document 1. The apparatus of Patent Document 1 is composed of a table on which a game board is positioned and mounted, and a combination of a nail holder mechanism, a hammer mechanism, and a nail supply mechanism arranged above the table, and a position for driving a nail by nail driving data; The game board is moved vertically and horizontally in the plane according to the order, the predetermined position of the game board is stopped under the nail holder mechanism, and the nail supplied from the nail supply unit to the nail holder mechanism is moved to the game board by the hammer mechanism. It is something that is driven into. In the above apparatus, the nail driving angle is set to a constant angle substantially perpendicular to the game board.

In recent years, there is a demand for a fine change of the nail driving angle depending on the position of the nail in order to control the dropping path of the steel ball that has been driven. In addition, it can be changed to an optimal nail driving angle in order to cope with subtle warping, expansion and contraction, etc. of a veneer board game board, or in response to a positional deviation or an angle deviation of a pilot hole in a resin game board. It became necessary to do so.
Therefore, the nail driving angle has been changed by inserting a spacer or the like on the mounting surface of the column that supports the entire assembly of the nail holder mechanism, hammer mechanism and nail supply mechanism. This has the problem that it takes time to insert a spacer or the like so as to have a desired angle. Therefore, although the device of Patent Document 2 has been developed, this discloses that the nail holding device 40 is tilted and the nail is driven in, but the tilt angle is not easily changed.

Reference is first made to FIG. 1 to describe the overall structure of the device according to the invention.
Reference numeral 1 denotes a base frame. A game board holding table 2 is disposed on the base frame 1. The game board holding table 2 includes a first portion 3 fixed to the base frame 1 and a second portion 4 which is moved on the first portion 3 in the XY directions by a moving device (not shown). Here, the X direction is a direction perpendicular to the drawing, and the Y direction is the left-right direction of the drawing.
On the upper surface of the second portion 4, a game board 5 into which nails are driven is placed at a predetermined position by positioning means (not shown).

  Reference numeral 6 denotes a nail driving mechanism holding frame. A fulcrum shaft 7 is fixed to the nail driving mechanism holding frame 6. The fulcrum shaft 7 is rotatably supported by two bearings 8 that are fixed to the base frame 1 at the outermost sides on both sides in the width direction extending in a direction perpendicular to the drawing. Can rotate around the center P of the fulcrum shaft 7.

Above the nail driving mechanism holding frame 6, a nail supply mechanism 10 for supplying a nail, a first nail holder 20 for holding the supplied nail, a nail received from the first nail holder 20, advancing and descending, and a nail A second nail holder 25 that moves to the hitting point and holds the nail and a hammer mechanism 30 that hits the held nail are disposed. The nail supply mechanism 10 includes a parts feeder 11 that stores a large amount of nails and a nail transfer part 12 that transfers the nail to the first nail holder 20, both of which are attached to the nail driving mechanism holding frame 6.
Since the first nail holder 20 is also composed of many elements, the details are omitted and the whole is shown as a polygon, but the chuck that actually holds the nail is shown as 21.
Since the hammer mechanism 30 is also composed of many elements, the details are omitted and the whole is shown by a square, but a hammer for actually driving a nail is shown by 31.
Note that the chuck 21 and the hammer 31 are set so that the nail is driven by being tilted by a minute angle indicated by α (around 5 degrees) even without adjusting the angle according to the present invention.

What is indicated by an up-and-down double arrow 100R is a first angle adjustment mechanism that moves to change the angle of the nail driving mechanism holding frame 6 with the center P of the fulcrum shaft 7 as a fulcrum.
What is indicated by an up-and-down double arrow 100L is a second angle adjustment mechanism that moves to change the angle of the nail driving mechanism holding frame 6 with the center P of the fulcrum shaft 7 as a fulcrum.
Details of the first angle adjustment mechanism 100R and the second angle adjustment mechanism 100L will be described in detail below for each embodiment.
In FIG. 1, reference numeral 50 denotes a control device that adjusts each mechanism, and stores data for nailing, for example, data such as at which position and how much to tilt. A storage device is also included.

2A and 2B are views for explaining the structure and operation of angle adjustment in the first embodiment. The first wedge is indicated by 110R, and the second wedge is indicated by 110L.
Two guides 111 </ b> R are attached to the lower surface of the first wedge 110 </ b> R, and the guides 111 </ b> R are slidably disposed on the rails 101 provided on the upper surface of the base frame 1. The first wedge 110R can be moved in the left-right direction in the figure by a ball screw 112R rotated by a first servomotor 113R. The first wedge 110R has a wedge slope 114R that rises to the right in the figure.

Similarly, the second wedge 110 </ b> L is provided with two guides 111 </ b> L on the lower surface, and the guide 111 </ b> L is slidably disposed on the rail 101 provided on the upper surface of the base frame 1.
The rod of the cylinder 119 attached to the wedge surface 114R is attached to the second wedge 110L, and the second wedge 110L is movable left and right by the cylinder 119. Similarly to the first wedge 110R, the second wedge 110L also has a wedge slope 114L that rises to the right.
A first follower 115R including a roller that can rotate on the right side of the fulcrum P is provided on the lower surface of the nail driving mechanism holding frame 6, and a similar second follower 115L is provided on the left side of the fulcrum P. The first follower 115R and the second follower 115L are schematically illustrated by circles.

When the angle is changed as shown in FIG. 2B (when α + β is set), the rod of the cylinder 119 is contracted and the wedge of the 114L is extracted once (moved to the right), and then the first wedge 110R is moved to the left. Move Then, the first follower 115R climbs the wedge surface 114L of the first wedge 110R. As a result, the right side of the fulcrum of the nail driving mechanism holding frame 6 is raised by β, the left side is lowered by β, and the nail driving mechanism holding frame 6 is moved by β minutes. Tilt to the left. Therefore, both the nail and the hammer 31 held by the nail holder 21 are inclined left by β. After that, the rod of the cylinder 119 is taken out, the second wedge 114L is moved to the left, and hits the second follower 115L, whereby the inclination of the nail driving mechanism holding frame 6 is maintained. Since the game board 5 is held at a constant angle, the nail is driven onto the game board 5 with an increased inclination.
Since the first wedge 110R and the second wedge 110L are connected via the rod of the cylinder 119, both can be moved left and right by the ball screw 112R rotated by the servo motor 113R. However, when moving, the rod of the cylinder 119 is contracted to release the tilt holding, and the left and right movement of the first wedge 110R determines the tilt angle, and the second wedge plays a role of holding the tilt by the advancement of the cylinder rod. The roles of the first wedge and the second wedge can be reversed.

Note that a pilot hole is previously machined on the game board 5, and the position is stored in the control device 50, and the game board 5 is positioned. The required nail driving angle at each position is also stored in the controller, and the amount of movement of the first wedge 110R according to the required nail driving angle is calculated, and the first wedge 110R is moved accordingly. And a desired inclination angle is obtained. The second wedge 110L moves forward and moves forward to maintain the inclination.
In FIG. 2 (A), the nail is usually driven at a nail driving inclination angle α, but in the case of FIG. 2 (B), the nail is driven at an inclination angle α + β including the inclination angle β of the nail driving mechanism holding frame 6.
In addition, the data stored in the control device 50 can be actually measured with a camera or the like in the prepared hole in the game board, and the data stored in the image processing device can be corrected to match the stored data. It is.

FIGS. 3A and 3B are views for explaining the structure and operation of angle adjustment in the second embodiment.
In the second embodiment, the lower surface of the nail driving mechanism holding frame 6 is provided with a first projection receiving portion 125R on the right side of the fulcrum P and a second projection receiving portion 125L on the left side of the fulcrum P.
The first linear motion device is indicated by 120R, and the second linear motion device is indicated by 120L. The first linear motion device 120R has a servo motor 121R fixed to the base frame 1 and a ball screw 122R that is driven by the servo motor 121R and is moved in the vertical direction in the figure, and a hemispherical portion 123R at the upper end of the ball screw 122R. Is attached and presses against the first protrusion receiving portion 125R.
The second linear motion device 120L is a large capacity cylinder.

  FIG. 3B shows that when the angle is changed (when α + β is set), the rod of the second linear motion device 120L cylinder is contracted to release the tilt hold, and the first linear motion device 120R is operated. The ball screw 122R is raised and the first projection receiving portion 125R is pushed by the hemispherical portion 123R at the upper end to raise the right side of the fulcrum P of the nail driving mechanism holding frame 6 to determine the inclination accuracy of β, and then the second linear motion The cylinder rod of the device 120L is raised and pressed against the second protrusion receiving portion 125L to maintain the inclination angle of α + β.

The amount of movement of the first linear motion device 120R according to the nail driving angle required by the control device 50 (see FIG. 1) is calculated, and the first linear motion device 120R is moved accordingly, and the nail driving mechanism holding frame is thus calculated. A desired tilt angle of 6 is obtained. The second linear motion device 120L plays a role of maintaining the tilt angle.
As in the first embodiment, in FIG. 3A, the nail is usually driven at the nail driving inclination angle α, but in the case of FIG. 3B, the inclination angle β of the nail driving mechanism holding frame 6 is set. It is driven with the added inclination angle α + β.

  The second linear motion device 120L may be a wedge mechanism directly connected to a cylinder shown in FIG. 4 described later and mounted on an LM (linear motion) guide, or may be a highly elastic spring mechanism shown in FIG.

FIGS. 4A and 4B are views for explaining the structure and operation of angle adjustment in the third embodiment.
This third embodiment utilizes a non-circular cam on one side and a wedge on the other side.
Shown at 130L is a non-circular cam. The non-circular cam 130L is coupled to a shaft 131L that is rotatably supported by the base frame 1, and a belt gear 132L is also coupled to the shaft 131L. The belt gear 132L is connected to a belt gear 136L coupled to a shaft 134L of a motor 133L fixed to the base frame 1 by a timing belt 137L.
In the third embodiment, on the lower surface of the nail driving mechanism holding frame 6, the first follower 135R including a roller that can rotate to the right side of the fulcrum P is provided on the lower surface of the fulcrum P, as in the first embodiment. A similar second follower 135L is provided on the left side.
By rotating the non-circular cam 130L, the distance from the center of the shaft 131L at the point in contact with the second follower 135L changes, and accordingly, the second follower 135L moves up and down to change the angle of the nail driving mechanism holding frame. . The wedge 130R is configured to move to the left and right as the cylinder rod 139 enters and exits in the same manner as the second wedge described above.

  FIG. 4B shows a case where the angle is changed (when α + β is set), the cylinder rod 139 is first retracted, the wedge 130R is moved to the right, and the nail driving mechanism holding frame 6 is held. To release. Next, by rotating the non-circular cam 130L and changing the nail driving mechanism holding frame 6 to a predetermined angle β, the second follower 135L is lowered in this case, and the angle of the nail driving mechanism holding frame 6 becomes α + β. The cylinder rod 139 is advanced again, the wedge 130R is moved to the left, and the angle of the nail driving mechanism holding frame 6 is held at α + β by coming into contact with the first follower 135R. As the angle holding mechanism, the direct acting mechanism directly connected to the cylinder shown in FIG. 3 or the highly elastic spring mechanism shown in FIG.

The amount of rotation of the non-circular cam 130R corresponding to the nail driving angle required by the control device 50 (see FIG. 1) is calculated, and the non-circular cam 130L is moved accordingly, and the desired nail driving mechanism holding frame 6 is desired. An inclination angle is obtained. The wedge 130R serves to maintain the tilt angle.
As in the first embodiment, in FIG. 4A, the nail is usually driven at a nail driving inclination angle α, but in the case of FIG. 4B, the inclination angle β of the nail driving mechanism holding frame 6 is added. It is driven at an inclined angle α + β.

5A and 5B are views for explaining the structure and operation of angle adjustment in the fourth embodiment.
The fourth embodiment has a rotation mechanism 140 that directly rotates the fulcrum shaft 7 passing through the fulcrum P of the nail driving mechanism holding frame 6. First. A fulcrum shaft 7 passing through the fulcrum P of the nail driving mechanism holding frame 6 is extended, and a first gear 141 is attached thereto. The first gear 141 meshes with a second gear 142 having a small diameter attached to an intermediate shaft 145 supported by a bearing (not shown) attached to the base frame 1. A third gear 143 having a large diameter is also attached to the intermediate shaft 145. The third gear 143 meshes with a fourth gear 144 with a small diameter attached to a shaft 147 of a motor 146 (not shown) attached to the base frame 1.

  When the shaft 147 of the motor 146 is rotated counterclockwise (counterclockwise), the fourth gear 144 is also rotated counterclockwise (counterclockwise), the third gear 143 is rotated clockwise, the second gear 142 is also rotated clockwise, The gear rotates counterclockwise, and the nail driving mechanism holding frame 6 rotates counterclockwise and falls to the left.

On the other hand, what is indicated by 140S is a highly elastic spring mechanism. The spring mechanism 140S receives a reaction force when nailing, and prevents the nail driving mechanism holding frame 6 from rotating more than the rotation mechanism 140 rotates.
The amount of rotation of the motor 146 is calculated according to the required driving angle of the nail in the control device 50 (see FIG. 1), and the motor 146 is rotated accordingly, and the desired inclination angle of the nail driving mechanism holding frame 6 is set. can get.

  As described above, the first to fourth embodiments have been described. In any case, the base frame 1 is installed in pairs at the outermost ends on both sides in the axial direction extending in the direction perpendicular to the drawing of FIG. The Also, based on these, various combinations not described can be made, and modifications can be made without departing from the gist of the present invention. For example, in the first embodiment, wedges can be used in opposite directions, and a combination of a wedge and a servo motor is also possible. In addition, the angle holding mechanism can be combined with a wedge mechanism directly connected to the cylinder, a linear motion mechanism using the cylinder, or a highly elastic spring device.

Note that it is possible to execute nailing while the data stored in the control device 50 is measured by the measurement device and corrected by the data processed by the image processing device, and a flowchart thereof is shown in FIG. So I will explain.
In step 1, nail data is read. In step 2, N is set to 1 as an initial value. In step 3, it is determined whether image measurement is necessary for the N-th nail. If an affirmative determination is made in step 3, the process proceeds to step 4. If a negative determination is made, the process jumps to step 7.
In step 4, the image is moved to the image measurement position of the Nth nail, in step 5, the image measurement of the Nth nail is performed, in step 6, the Nth nail position correction calculation is performed, and the process proceeds to step 7.
In step 7, the nail is moved to the N-th nail position. In step 8, the N-th nail is driven and the process proceeds to step 9.
In step 9, it is determined whether or not the final nail driving has been completed. If a positive determination is made, the process proceeds to step 10 to return to the origin position, and then proceeds to step 12 and ends. If a negative determination is made, N is incremented to N + 1 in step 11 and the process returns to step 3.
